I seem to change my mind every five minutes. I'm booked in for an abortion in two weeks.
You are in a difficult situation and all the circumstances are pressurising you towards abortion. The battle you describe between your head and your heart is a very real one. Your head tells you the rational option at this point in your life, but your instincts and conscience are already fearing the guilt and regret an abortion may bring. It is important to listen to both.
Think about your circumstances and whether there are options for nursery or childcare you could use to keep your job. Remember that circumstances change all the time and so you should be careful about making a decision just on what is happening in your life at the moment.
Your heart is the core of who you are as a person and if you choose to ignore what your heart is saying you may feel you have betrayed yourself.
It may help you to talk this through with someone before you make your final decision. You can ring the national helpline 0300 4000 999 and speak to a trained advisor. They may also be able to put you in touch with a pregnancy centre in your area.
If you are still undecided by the time of your appointment it is better to postpone it. This will not mean that this door is closed to you, but it is important not to be pressurised into your decision.
